摘　　要：航发叶片工艺规程和数据信息采用二维CAD软件编写和绘制,生成的DWG工艺文件难以进行简便和高效管理。提出了叶片CAD工艺信息数字化的管理方法,首先,对叶片图纸工艺规程和数据信息进行关联性分析,采用最小二乘法完成图纸尺寸定位,根据坐标确定关键字位置,实现判断叶片工艺卡片类型;随后,判断识别需要的单元格工艺信息,利用正则算法进行文字排序,并识别处理特殊字符,调整后获得准确叶片工艺信息数据。实践结果表明,该方法能够快速、稳定地识别出CAD工艺文件中的工艺信息数据,为工厂实现智能制造数字化提供了图纸管理方法的应用参考。The process planning and data information of aeroengine blade are written and drawn by 2D CAD software.The generated DWG process files are difficult to manage easily and efficiently.In this paper,the management method of blade CAD process information digitization is proposed.Firstly,the relationship between blade drawing process specification and data information is analyzed.The least square method is used to locate the size of the drawing,and the key position is determined according to the coordinates to judge the type of blade process card;Then,the process information of the cells needed for recognition is judged,the text is sorted by using the regularization algorithm,and the special characters are recognized and processed to obtain the accurate blade process information data after adjustment.The practical results show that the method can quickly and stably identify the process information data in CAD process files,and provide the application reference of drawing management method for the factory to realize intelligent manufacturing digitization.
